Biomom/baby mom issues
First I will begin with short history of my SO and I being together for almost 5 years now. Collectively we have 4 kids together, two of which are skids. This year he made the executive decision for them to live with us full time claiming that their bio mom is unfit. The kids were underweight and the younger has behavioral issues. All the while the entire load is placed upon me, the SAHM who is achieving a degree in Nursing. Fast forward to Christmas Day where she is coming to pick the kids up and their grandmas house where we are all eating and she just lets herself in and the two of them seem to be the best of friends. I am in no way insecure, I just find it so hard to see them this way with all of the hell she puts us through, and all of the crap he talks/claims to feel about her.
My day just feels ruined. I do not want any sort of fake relationship/forced relationship with her. I'm forced to try and have a relationship with the younger skid 4 , whom his mom is his #1. I just find it quite unfair that he treats me however with no form of discipline. I guess I am in need of a pep talk because at this point I am just ready to say that this is not at all what I want because I do not want any sort of dealings with her AT ALL. I understand this may be immature, however, I have little interest in playing happy face with toxic people with terrible and shorty intentions towards me and their kids. I feel I could be much better alone, with my children without the added stress of this all....
